If you can get 5 cans for 4$, then how many cans should you advise the chef to buy to make enough spagetti for 240 campers?
The chef should get 200 cans of sauce for the 240 campers. 240 ÷ 6 = 40, 40×5 = 200.
How much will it cost?
200 cans will cost $160.
3.2 Follow Up
1. There is another place that can sell cans, EATMORE sells 7 cans for 6$. Is that a better buy? Explain.
CANNEDSTUFF is a better buy than EATMORE.
2. Gus divided 7 by 6 and got 1.66666667. He also divided 6 by 7 and got 0.857143, What do each of these numbers mean?
The problem 7 ÷ 6 will show how many cans $1 can buy. The problem 6 ÷ 7 will show how much 1 can costs.
